<p>A rotative force is sufficiently stored in a force storing spring to reliably start an engine without depending on the value of starting resistance of the engine. A small engine starting device (1) has a rotation restricting means (40) which is engaged with a pulley (8), to restrict the rotation of a drive cam (11) until the rotative force applied to the drive cam (11) reaches a starting rotative force which is necessary to start the engine. The rotation restricting means (40) has a guide shaft (44b) formed in parallel with a rotary shaft of the pulley (8); a stopper plate (53) which is rotatably provided in the guide shaft (44b), and can be engaged with the drive cam (11) and rotate in a direction in which the stopper plate (53) is released from the drive cam (11); and a stopper means (43) which restricts the rotation of the stopper plate (53) until the starting rotative force is applied to the stopper plate (53) via the drive cam (11).</p> |
